I've taken the liberty to copy the posts below to the new UM3X thread as I believe they may now be more useful over there. So perhaps theory_87 can carry on with his/her first impressions there?

Added the much need sparkle that se530 lack. but not to the extend of tf10p. I just thought i end my portable journey with T1 but um3x force me to open my wallet once more.

Than either you go um56 or ES3x, else stay with ck100.

All my finding is base on um3x with um56 hence I do not know how universal ear sleeves will fare

UM3X Specifications

Sensitivity: 124dB/mW

Frequency response: 20 Hz -18 kHz

Impedance: 56 ohms

Driver: Three balanced armature drivers with a passive three-way crossover.

Yes I appreciated the fact Mike sent the special UM3X e-mail offer to people who had formally bought the W3s from him. That is a sign of good customer service and I suspect was a profitable move. I'm sure he had some people jump on it...I know I did!

After reading some of the reviews that have been coming in I have a feeling the UM3X is going to be a winner in some circles. I should have paid extra for the next day shipping…lol.

Cheers,

Not just people who bought the W3 from him, but other customers of theirs also got the email offer (like me).

theory_87,
To which kind of music do you mostly listen to? What do you think about the ACS T1 in comparison with the UM3X? And why do you think UM3X are better?

LOL, you've just moved to another thread; I thought you had decided already??is this an indirect question about the ES3X?? make the decision, it'll be a lot healthier than doing your head in trying to get the 'perfect' IEM by collecting many different people with different ears and differing opinions
